<p><span class="user-group-mention" data-user-group-id="1172">@WG-async-foundations</span> Sorry for late notice, but I won't be able to make the meeting today due to a scheduling conflict. I think we'll have to cancel, but I'm setting aside time later today to do issue triage in this stream.</p>

<h2>#[track_caller] does nothing on async fns <a href="https://github.com/rust-lang/rust/issues/78840">#78840</a></h2>
<p>The suggestion to forward <code>#[track_caller]</code> on to the poll function makes sense to me. Not prioritizing this since it's blocked behind closure support and doesn't seem oft requested.</p>

<p>Okay, I think that's all for now. Just a couple more recent ones left but it might be good to handle those with the full group.</p>
